It was pretty cool last night in Boulder, but fortunately my first Amazon Fresh order came packed in dry ice this morning. So I was able to release lots of CO2 and warm the planet by several degrees.
Success of my experiment was confirmed by official US government thermometers, which showed seven degrees warming in the half hour after I started releasing the CO2.

Every good climate scientist knows that correlation equals causation, so I have confirmed the dangers of global warming.
